AI Technical Summary

Benefits of technology

This configuration minimizes voltage drops across the thin and large-sized electrodes, enabling more efficient power delivery to the organic emission layer, thus enhancing the performance and scalability of OLED displays.

Problems solved by technology

However, because the second electrode formed as a thin film is formed over the entire area of the substrate in the front emission type OLED display, a voltage drop occurs in driving power passing through the second electrode for driving the organic emission layer due to electrical resistance of the second electrode.

Abstract

An OLED display includes a substrate; a first electrode on the substrate; an organic emission layer on the first electrode; a second electrode on the organic emission layer; an organic layer on the second electrode and corresponding to the first electrode; and an auxiliary electrode contacting the second electrode and neighboring the organic layer.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to and the benefit of Korean Patent Application No. 10-2013-0000181 filed in the Korean Intellectual Property Office on Jan. 2, 2013, the entire content of which is incorporated herein by reference.BACKGROUND[0002]1. Field[0003]The described technology relates generally to an organic light emitting diode (OLED) display.[0004]2. Description of the Related Art[0005]A display device is a device that displays an image, and currently, organic light emitting diode (OLED) displays are in the spotlight.[0006]Because the organic light emitting diode (OLED) display has a self-light emitting characteristic so that a separate light source is not required, unlike a liquid crystal display (LCD), a thickness and a weight thereof may be reduced. Further, because the OLED display has high quality characteristics such as low power consumption, high luminance, and high response speed, the OLED display is appropriate for use i...
